But there is so much more we could create that is original. Why revisit the Genesis cave? Go forward not backwards, in said example you could mention project Genesis and have a story where someone has aquired a possible Genesis device maybe by time travel, or maybe Kruge's mistress Valkris had transmitted a copy to a secret faction of Klingon intelligence.

Use the I.P. for reference and launch your own ideas "based" on some of the things on the show. If people keep making yet another version of Kobayashi Maru, or a sequal to an episode, it just isn't taking advantage of what we have here.
